Python is one of the most common coding languages of 2015, according to numerous websites. Python is also an object-oriented and open-source language, as well as being a high-level and general-purpose programming language. At the same time, Python was used by a good number of developers worldwide to create GUI applications, websites, and mobile apps. The differentiating element Python brings to the table is that, by writing fewer and readable code, it allows programmers to flesh out concepts. Additionally, developers may take advantage of many Python frameworks to minimize the time and energy required to create large and complex software applications.

A variety of high-traffic websites currently use the programming language, including Facebook, Yahoo Groups, Yahoo Maps, Linux Weekly News, Shopzilla, and Web Therapy. Python also finds great use in developing gaming, political, scientific, and educational apps. Developers, however, still use various programming language versions. According to Python ‘s usage figures and market share data reported on W3techs, 99.4 percent of websites are using Python 2, while just 0.6 percent of sites are using Python 3. That’s why knowing various versions of Python, and its development over many years, is essential for each programmer.
How Has Python Been Evolving over the Years?
Conceived as a Hobby Programming Project
While being one of the most common coding languages of 2015, in December 1989, Guido van Rossum had initially been conceived Python as a hobby project. As Van Rossum’s office was closed during Christmas, he was searching for a leisure project during the holidays to keep him busy. He decided to build a new scripting language interpreter and called the project as Python. Thus Python was initially planned as a successor to the language of ABC programming. Van Rossum had made the code public in February 1991 after writing the interpreter. Now, however, the Python Software Foundation operates the open-source programming language.
Version 1 of Python
In January 1994, Python 1.0 released. The big update included a range of new features and functional programming tools, including lambda, filter, map, and reduction. Version 1.4 released with several new features, including keyword arguments, built-in support for complex numbers, and a basic form of hiding data. Two incremental updates followed, version 1.5 in December 1997 and version 1.6 in September 2000. Python version 1 lacked the features that common programming languages of the time had to offer. But the initial versions provided a stable basis for a futuristic and robust programming language to evolve.
Version 2 of Python
Python 2.0 was released in October 2000 with the new comprehension function for the list and a garbage collection method. Inspired by other functional programming languages such as Haskell, the syntax for the list comprehension feature was. Yet unlike Haskell, Python 2.0 gave alphabetic keywords a preference over punctuation characters. Besides, the garbage collection system gathered reference cycles. Many smaller releases followed on from the main release. These releases added several functions to the programming language, such as supporting nested scopes and unifying the classes and types of Python into a single hierarchy. The Python Software Foundation has already announced the absence of a Python 2.8. The Foundation will, however, provide funding for the programming language version 2.7 until 2020.
Version 3 of Python
In December 2008, Python 3.0 released. This came along with a range of new features and enhancements, along with a range of discontinued features. The deprecated features and backward incompatibility make Python version 3 entirely different from earlier updates. Too many developers are still using Python 2.6 or 2.7 to take advantage of the deprecated features from last big release. Yet Python 3’s new features made it more modern and popular. Some developers have migrated to programming language version 3.0 to take advantage of these cool features.
Python 3.0 replaced print statement with the built-in print) (feature, thus enabling programmers to use custom line separator. It also simplified the rules of comparison order. Unless the operands are not ordered in natural and logical order, then a TypeError exception may now be created by the ordering comparison operators. The programming language version 3 additionally uses text and data instead of Unicode and 8-bit strings. By default, it represents binary data when treating all code as Unicode as encoded Unicode.
As Python 3 is incompatible backward, the programmers are unable to access features such as string exceptions, old-style classes, and implicit relative imports. The developers do need to be familiar with the syntax and API changes. We can use a “2to3” method for the smooth migration of their code from Python 2 to 3. By feedback and alerts, the tool illustrates incompatibility and areas of concern. The comments help programmers make code improvements and update their current apps to the new programming language version.
Latest Versions of Python
Currently, programmers can select either the Python version 3.4.3 or 2.7.10. Python 2.7 allows developers to take advantage of improved numerical handling and standard library enhancements. The version further simplifies the migration of developers to Python 3. Python 3.4, on the other hand, comes with some new features and library plugins, enhancements to security, and changes to CPython ‘s implementation. Nevertheless, in both the Python API and the programming language, a variety of features are deprecated. In the longer run, developers will still use Python 3.4 to make use of the service.
Version 4 of Python
It is expected that Python 4.0 will be available in 2023 after Python 3.9 launches. This will come with features helping programmers easily move from version 3 to 4. When they gain experience, the experienced Python developers can also take advantage of a range of backward-compatible features to modernize their current applications without putting any additional time and effort into it. The developers have yet to wait several years to get a good image of Python 4.0, however. We must however track the latest releases in order to quickly move to the common coding language version 4.0.
